Abstract:

In this talk, challenges incooperative multiple-input multiple-output (MIMO) wireless channel modelling willfirst be reviewed. Then,a novel unified channel model framework is proposed for cooperative MIMO wireless channels. The proposed model framework is generic and adaptable to multiple cooperative MIMO scenarios by simply adjusting key model parameters. Based on the proposed model framework and using a typical cooperative MIMO communication environment as an example, we derive a novel geometry-based stochastic model (GBSM) applicable to multiple wireless propagation scenarios. The proposed GBSM is the first cooperative MIMO channel model that has the ability to investigate the impact of the local scattering density (LSD) on channel characteristics. From the derived GBSM, the corresponding multi-link spatial correlation functions are derived and numerically analyzed in detail. The talk will end with discussing future challenges in MIMO channel models.
